Automatic hinge characterized by comprising a piece in the form of a box embedded in the inner face of the door frame and having an internal axis on which the second part of the hinge is articulated, which is angled at a right angle and fixed by its free end to the inner face of the door, between these two articulated parts being interposed a compression-working spring arranged so that, when the hinge is rotated in one direction or the other to open or close the door, it oscillates between two extreme positions in which it tends to keep the door completely open and completely closed respectively, passing through an intermediate position of unstable equilibrium in which its axis intersects the articulation axis of the hinge.
